The joke was funny, the second joke is ok (the end is his worst part) and voice adding was a good idea, now let's have scores:

graphics 4/10: you have your own style, but you can improve on details, work on it.
animation 1/10: almost slides like, this is your weak point at the moment.
music and voices: 5/10 average, music is not bad, voice acting must stress more the difference between characters, Luke needs a different voice and more voice acting about his feelings.
story and humor 8/10: the final part can be improved but I see good ideas and the will to put them in flash in a funny way, keep it up.

Yoda says:

4,5/10 your average is but in five turns (encouraged your desire to improve should be...yes...). On animation work and on drawing a bit, just your style develope.
Let voice acting lower your scores, not.

look dont get me wrong, i found it quite funny actually. short and sweet yet it left me a bitter taste in my mouth. why? well the quality of it was...well it lacked. I may understand about the audio part but, improve your drawing skills, at least put some effort into it. but non the less it was pretty funny. thats the only thing that gives this submission a 4. 1 for quality and 3 for funny.
